The Chile international has been settling into life at Old Trafford after having signed for the Red Devils from the Gunners at the start of the year.
Arsenal opted to cash-in on Sanchez rather than risk losing him on a free transfer in the summer and the Gunners signed Henrikh Mkhitaryan as part of the same deal.
However, it has been something of a slow start to life for Sanchez at Old Trafford following his move to Manchester United from the north London club.
The 29-year-old has been a regular fixture in the team but seems to be struggling to produce his best form for Jose Mourinho’s men.
And former Manchester United star Ince feels that Sanchez could already be regretting his decision to move to the Red Devils from Arsenal in the winter window.
Speaking to Paddy Power, Ince said: “Sanchez keeps trying to do things, and make things happen, but the more he does the worse the team gets. I’d bet that he probably wished he’d waited until the end of the season and gone to another team.
“It’s evident, from watching United since he joined, that he doesn’t suit how Jose Mourinho plays football. You could see him fitting in at Manchester City better.
“Maybe Jose’s plan is to bring in players that do suit the way Lukaku, Sanchez and Pogba play, but how much more can you spend to satisfy other players?
“They need to look at themselves and how they’re playing, rather than relying on others to help them out.”
Sanchez will be hoping to help fire Manchester United into the semi-finals of the FA Cup on Saturday evening when the Red Devils host Brighton and Hove Albion in the last eight.
The Red Devils were dumped out of the Champions League on Tuesday night after a shock 2-1 loss to Sevilla.
